Golf club head

ABSTRACT

A golf club head includes a ferrule at one side for connecting a club, a striking face formed in a front side, and an angle indicating device fitted in an upper center portion of the club head easily seen by a player. The angle-indicting device has a pointing member and an angle indicating marks. Then a golf player can look at the point of the angle indicating marks where the top of the pointing member is pointing to, and adjust and confirm the angle between the striking surface of the club head and the ball according to the condition of the courses of the gold link. Thus a player can strike a ball with the best angle to achieve striking stability by means of the angle-indicating device.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This is a Continuation-in-part application of Ser. No.09/885,965, filed Jun. 22, 2001, entitled “Shock-Absorbing Golf-ClubHead”.

[0003] This invention relates to a golf club head, particularly to oneprovided with an angle-indicating device for a golfer to strike a ballby adjusting the striking angle and action by checking the point of theangle indicating marks pointed by a pointing member of the device so asto stabilize striking a ball.

[0004] 2. Description of the Prior Arts

[0005] The number of people playing golf has been increasing as thissport has been growing popular, and beginners always learn its techniquefrom experienced players about striking postures, angles of the goldclub to a ball, etc. incessantly making practice to upgrade strikingstability. In teaching techniques of playing golf, a tutor may at firstverbally explain various key points of correct methods for striking, andlearners have to actually hold a golf club and strike a ball personallyto gradually acquire better tricks, spending not a few time to correctand adjust their own postures and striking actions. The stabilizedstriking always affects the flying direction of a ball, but it may bedifficult to maintain the same striking point of a ball and the strikingangle to a ball. The main reason of this drawback lies in the golf clubhead not provided any indicating marks to let players to confirm thestriking point and the striking angle of a golf club head to a ball, sobeginners or not so experienced players cannot strike a ball accurately.

SUMMARY OF THE INVENTION

[0006] The purpose of the invention is to offer a golf club headprovided with an angle indicating marks for a player to adjust thestriking angle of a gold club head to a ball for enhancing strikingstability.

[0007] The feature of the invention is an angle indicating deviceprovided in an upper portion of a club head to be easily seen by aplayer, and the angle indication device includes an pointing memberrotatable with a gravity center positioned very low to point one ofplural indicating marks formed on an upper surface of the device. Then aplayer can look at the pointing member and adjust its position to one ofthe indicating marks for the correct angle of the striking surface ofthe club head towards the ball.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] A preferred embodiment of a golf club head 1 in the presentinvention, as shown in FIG. 1, includes a ferrule 11 at one side forconnecting a golf club 12, a striking surface formed in a front side,and an angle indicating device 2 fixed in an upper surface nearlyparallel to the striking direction.

[0017] The angle indicating device 2 consists of a supporting case 21almost U-shaped to have an interior hollow defined by two lengthwisevertical walls, two opposite side walls, a closed bottom and an open topside, and a plurality of angle indicting marks 211 shown by means ofslender cut lines, letters, figures, etc. Further, the angle indicatingdevice 2 consists of a rotary shaft 22 positioned between the twolengthwise sides and a pointing member 22 rotatably supported by therotary shaft 22 to have its center of gravity very near to the bottom tokeep its top end always pointing to the upper side, for example, shapedlike a water drop, a pointed cone, an inverted cone or a round shape.Its top end is not necessarily pointed, but a preferably bright coloredobvious mark 231 to be easily seen. FIG. 2 shows the angle indicatingdevice 2 positioned in a golf club head 1, with the pointing member 23having its top pointing upward to one of the indicating marks 211 on oneof the two longwise walls of the supporting case 21 because of its lowcenter of gravity attracted by the terrestrial gravitation. The angleindicating marks 211 can not only made on the upper surface of either ofthe two lengthwise walls of the supporter 21, but on any location on theupper surface of the club head 1 near the pointing member 23.

[0018] In using, a golf player stands at a proper location for strikinga ball, with the striking surface of his/her club head placed near aball 3, taking measure by eyesight and adjusting the bodily position tothe best position and the best angle for striking. In the process ofmeasuring and adjusting, the player looks at one of the indicating marks211 pointed by the pointing member 23, checking the angle between thestriking surface 13 and the contacting surface of the ball 3. Forexample, as shown in FIG. 3, when the top end 231 of the pointing member23 points the center one of the indicating angle marks 211, the strikingsurface 13 of the club head 1 is vertical against the ball 3. Thisstriking angle may let a club head strike the ball 3 to a mediumdistance, so a player makes practice with this angle and becomesfamiliar with this striking technique and then proceeds to practicestriking for a long distance and a short distance.

[0019] Next, as shown in FIG. 4, in order to strike a ball to acomparatively long distance, the striking point is to be a little lowerthan the center of gravity of a ball 3. Then a player holds the club tolet the club head 1 with its striking surface 13 a little raised up,with the pointing member 23 having its top end pointing to one of theangle indicating marks 211 near the striking surface 13 to let thestriking point a little higher than the center of gravity of the ball 3.Then the ball may fly high to a comparatively long distance.

[0020] Next, as shown in FIG. 5, in order to strike a ball to acomparatively short distance or on a down slope, the striking surface 13has to slope down, with the rotary shaft 22 functioning as a pivot tolet the pointing member 23 rotate. Then the top of the indicating member23 points to a rather far point of the indicating marks 211 from thestriking surface 13. Therefore, the ball 3 may fly in a direction almostnear the ground, reaching a short distance from the striking point.

[0021] After a player finishes practice, all the golf clubs are placedin a golf club bag 4 as shown in FIG. 6, with the club heads 1 locatedto extend out of the bag 4, with the grips (not shown in the Figures)located downward in the bag 4. At this condition, the pointing member 23rotates with the rotary shaft 22 as a pivot, the bottom of the pointingmember 23 points to the angle indicating marks 211 with its top still atthe upper side pointing to the bottom of the club head 1. Then the topof the pointing member 23 is hidden in the head 1, not to be contactedby fingers, safe and convenient.

[0022] Utilizing the angle indication device 2 of the invention, a golfplayer can look at the top of the pointing member 23 located between thetwo walls of the supporting case 21 for controlling the striking angleand the flying distance of a ball after struck. At the same time, as theangle indicating device 2 has the angle indicating marks 211, a playercan look at the top of the pointing member 23 and knows the location itpoints for speculating the possible effect of striking. Then the playercan be aware of the distance a ball flies by looking at the location ofthe indicating marks 211 pointed by the top of the pointing member 23 bylong-term practice and experience. This function of the club head isvery difficult to be achieved by conventional golf club heads, assistinga player learn and obtain the hints of striking techniques in a shortterm.

[0023] Another characteristic of the invention is that the top of thepointing member 23 is brilliantly colored or painted with fluorescentpowder or the like, making the obvious mark 231. So a player cannot failto find out the angle indicating marks 211 the top of the pointingmember 23 points to, adding much convenience for finding the best anglefor striking a club head. Especially, a maker can make the indicatingmarks very stark and obvious for a player to depend on them forpracticing. Maybe the angle indicating marks can be made extremely clearfor tall persons, as shown in FIG. 7. In addition, the angle indicationmarks can be slender cut lines, alphabets, characters, figures, orsigns.
